AP7315D-26FS4-7B

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AP7315D-26FS4-7B is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a 2.6V output with a guaranteed maximum load current of 150mA. It operates within an input voltage range of 1.7V to 5.25V and features a typical ripple rejection ratio of 75dB at 1kHz. The device incorporates an internal discharge resistor for rapid output voltage decay upon shutdown. Packaged in the X2-DFN1010-4 footprint, it supports an operating ambient temperature range from -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify that the FS4 suffix corresponds to the X2-DFN1010-4 package type required for your PCB layout. Confirm the 'D' designation indicates the inclusion of the output discharge feature, as this affects shutdown behavior compared to non-discharge variants. Ensure the ordering suffix matches the specific tape and reel packaging quantity specified in the manufacturer's documentation.
